MEANS' FOR FILTERING AND COOLING WATER.

GPECIFICATION forming part of Letters Patent No. 500,528, dated June 27, 1893.

' Application filed June 13,1891- Serial No, 396,191. (No model.)

To all whom it may concern:

Be it known that 1, JOHN M.-BRU0E, a citi- Zen of the United States, residing at Pittsvices for cooling and filtering water for'domes tic use, in which the water from the main passes through a cooling chamber embedded in the earth, and also through a filter, before it is used, and consists .in certain peculiaritiesin the construction, arrangement and combination of the several parts, substantially as hereinafter described and particularly pointed out in the subjoined claims.

In the accompanying drawings: Figure 1 is a View, partly'in section, of an apparatus constructed in accordance with my invention. Fig. 2 is an enlarged side elevation of the union between the filter and the pipe-for drawing water direct from the same. Fig. 3 is an enlarged View of the pipe leading from the cooler into the dwelling showing the non-conducting material for said pipe. Fig. 4 is a sectional elevation of a filter of somewhat different construction from that shown in Fig. 1, which may be used if desired.

1 designates an iron cylinder which is closed at the base and fitted at the top with an airtight cap 2. This cylinderis embedded inthe moist earth in a suitable position beneath a dwelling house, 3, or at any other convenient point after the manner shown at Fig. 1 on the drawings. Extending from the street main or other conduit is a pipe 4 which is connected to a filter 5 by the short branch pipe 4 and with the cylinder 1 by the pipes 7 and 7, said pipe 4 entering thetop of the filter 5 and the pipe 7 entering the cylinder 1 through the cap 2 thereof. A pipe 6 leads from the bottom of the filter up to the pipe 4. Leading upward from the interior of the cylinder 1 is a pipeS which is conductedinto the dwelling, or other point or place of delivery, and said pipe is covered with a non-conducting material 16, which will exclude the atmospheric or other heat, and keep the water therein at the same temperature as that of the cooler. The pipe 4, where it is joined with the branch pipes 4 and 6,'is provided with suitable three-way cocks 12 and 12*.

From the above it will be seen that when the cook 12 is turned so as to open communication of the main portion of the pipe 4 with the pipe 4 but close the pipe 4 between said cock and cook 12 and said cock 12 turned so as to open communication between pipes 6 and the portion of the pipe 4 in advance of said pipe 6, the water from said pipe 4 will fiow through pipe 4 into and through the filter thence through the pipes 6, 7 and 7 into the cooling chamber 1, from which it is drawn, as required, through the pipe 8.

Formed integral with the lower side of the cap 2 and projecting into the cooling chamber l is a tube 2, open at its bottom but closed at its top by the cap 2. This tube forms an air chamber, which provides an air cushion at the top of the cooling chamber. This air cushion is not intended to assist noris it capable of assisting a continuous flow of water, butits reaction upon the turning of the spigot to draw water from the cooling chamber 1, is sufficient to aid in filling a glass or a pitcher of water, which is important as the filter through neglect frequently becomes so clogged that the water will not flow freely, in which event the air cushion will meet the difficulty by prompt action to the extent of its capacity. It also receives the shock, and thereby prevents the ramming, incident to the closing of the spigot.

In certain cases the temperature of the Water is not important and it is therefore advisable to provide a means whereby the water can be drawn direct from the filtering chamber without disturbing that in the cooling chamber, thereby preventing excessive use of the latter. To this end I have provided a pipe 14 which extends from a suitable place of delivery to the pipe 4, being connected to m'ally closed.

said pipe, between the cock 12 and the pipe 7, by a suitable union 15, and having a suitable cook 01' valve. Thus,'v'vh'en it is desired to draw large quantities of water direct from the filter, it, can be done by simply turning the valves or cocks 12 and 12, so as to establish communication of the pipe 4 with the filter and with the pipes 6 and 14, and by cutting off communication of the pipe 4 with the pipe 7.

Should it be desired to cleanse the filter it can be done by turning the cook 12 so as to open communication of the pipe ;6 with the filter and close communicationof the filter with the cooler, and turning the cook 12 so as to close communication through the pipe 4, thereby directing the water-from the main to the filter through the-pipe 6 and causing it to enter under the bottom of the .filteringmaterial, the dirty water and refuse passing through a pipe 17 leading from the side of the filter and having suitable connection with a sewer. Said pipe 17 isprovided with a suitable valve or cock as 18 for keeping it nor- In operation the water is first filtered and discharged into the coolingchamber 1, where itis allowed to remain until its temperature is the same as that of the surroundingearth, and the'water is forced upwardintothe dwelling 3 by the pressure in the supply pipe 4. By thus first filtering the water before it enters the'cooler, the greater part if not all of the sediment'and foreignmatter in the water, is prevented from reaching the cooling chamber, but should any foreign matter or sediment reaehthe cooling chamber it will be blown out by opening the valve 11 in a pipe 11, which pipe reaches almost to the bottom of the cooling chamber, andallowing the city pressure to drive said refuse through said pipe.

- Having now described my invention, I claim- 1. The combination with the cooling chamber embedded in the ground, a pipe connecting said cooling chamber with the water-supp1y, a pipe connecting said cooling chamber with a point of delivery, and an air-tight cap for the upper end of said cooling chamber, said cap having a tube projecting downward into the upper portion of the cooling chamber from its under side, said tube being open at its lower end but closed at its upper end by said cap, substantially as described, thereby forming an air cushion at the top of the cooling chamber, whichwill aidin drawing a limited quantity'of waterand also receive the shock and prevent ramming incident to the closing of the spigot.

' '2. The cornbinatiomina water filterer and cooler, of a filtering chamber, a pipe leading from the water supply thereto, a cooling chamber embedded'in the ground and connected with said filtering chamber, a pipe extending from saidcool'ing chamber to aplace of delivery, and an air-tight cap for said cooling chamber, said caphavinga tubeprojecting into the upper portion of said cooling chamber from its underside, thereby forming -an air cushion at the top of said cooling chamber, substantially as described' and jfor the purposes specified.

In testimony that Iclairn the foregoing I hereunto affix my signature' this 9th day of June, A. D. 1891.
